Meaning of the settings
Control function Flow control or open loop operation
Control function Y Type of control. If the control function is interpreted as
inverted, then this will be displayed.
Characteristic curve The EPIV controller works with either an equal-percentage
or a linear characteristic curve.
Characteristic curve off means "linear", characteristic curve
on means "equal percentage".
The two characteristic curves (feedback U5 and control
function Y) are always either simultaneously activated or
simultaneously deactivated.
Feedback U5 Type of feedback signal (conventional operation)
Nominal range Nominal position range within the mechanical
limits
Valve size Size of the valve; is set by Belimo. If the specified volumet-
ric flow scale with respect to the valve size has been
changed from the factory setting, then the label marked
"Scaling adjusted" will appear.
Volumetric flow settings Operating volumetric flow settings: V'nom / V'max
(only V'nom in open loop operation)
Synchronisation at Stop position 0% or 100%
Bus fail position Position in the event of MP communications failure
Power ON Behaviour/Function when switching on the device
or after a voltage interruption, respectively
Gear release button Function when the gear release button is pressed
Firmware Software version of the EPIV controller
Config table ID Identification of the configuration table of the EPIV
Operating time Number of hours during which the actuator was connected
to the supply
Active time Number of hours during which the actuator was mechani-
cally moving and connected to the supply
Stop & Go ratio Ratio of active time/operating time in percent. A high Stop
& Go ratio (red) indicates that the control is unstable.
The following additional settings appear when EPIV is combined with Super Cap:
Power Fail-/Power off
Pos.
Actuator position after failure of the supply voltage
Power fail Delay Time after the failure of the supply voltage and before the
actuator begins to move to the emergency setting position.
Power fail Count Number of voltage interruptions
